.Application June 3 Claims.

The present invention relates to burners and has for its object theprouision of a device wherein fluid fuel such as gas. or oil may becompletely consumed so as to leave practically no soot or smoke. l

object of the present invention may receive a supply of air prior toentering the burner, and in which combustion chamber and a supplementarycombustion chamber may be provided.

A still `further object is to generally improve ers o the typeindicated.

With the above general objects in viewand others that will appear as theinvention is better understood, the same consists in the novelconstruction, combination and arrangement oi parts hereinafter morefully described, illustrated in the accompanying drawing and pointed outin the appended claims.

In the drawing forming a cation, and in which like designatingcharacters refer to corresponding parts throughout the several views;

Fig, l is a vertical cross-sectional view through the burner; y

Fig. 2 is a cross-sectional view on horizontal plane on line 2--2 ofFig. l; and

Fig. 3 is a horizontal cross-sectional view'on line 3-3 of Fig. l.

Referring to the present drawing in detail there is shown therein acylindrical casing l@ having a bottom il. Centrally of said bottom around opening l2 is provided which is deiined by collar i3 integrallyformed with said bottom ll, and which collar projects above and belowsaid bottom il. Set over said opening l2 is cap 96,' which, by its lowerend is adapted to tric-su tionally engage and contact the outerperipheryor the upper end of said collar lit, by virtue o which arrangement saidcap lli remains in a rigid engagement with said bottom li. Cap le orlarger dimensions than cap ill is positioned over the latter, and by itslower end set with in an annular groove it made in hottom il, wherebysaid cap l5 likewise remains in a rigid relation with bottom il. Saidcap ifi is in a concentric and'spaced relation with cap iii so as toprovide therebetween a preheatirlg chamber il for the purposehereinaiter described.

Cap lll adjacent its lower end is provi@ a plurality oi circumferentialrows oi al itl, which are disposed above the upper t tion of collar it.Cap l5 is provided with a pair of the present invention the constructionoi burn- Chicagc, Ill., assignor of one-half to Julius Bandyga; C

(Cl. h-9i) of circumferential rows of apertures i9. These latterapertures l! are made at points which are below and above apertures i8in cap li on horl zontal plane. In other words apertures IB are not inalignment on horizontal plane with apertures I9. This arrangement ismade for the purpose of causing the air passing through apertures I8 tofirst strike the opposite solid sur tace of cap l5 so that the same maycirculate within preheating chamber il before the same finally passesinto the burnerthrough apertures it.

Substantially the upper one-halt portion-oi cylindrical casing l@ isreduced in thickness so as to denne on the inner periphery thereofshoul- 1 der 20 upon which an annular baflie plate 2l part oi thisapplimay be positioned. Said 'bams plate 2l has a round opening 22 inits center oi a diameter substantially vcorresponding to diameter of capI5 and is disposed above said cap lli. integrally formed with saidbaille plate tl and downwardly projecting from the marginal edge definedby said opening 2t is a plurality o spaced plates 23 which are olarcuate formation on horizontal plane. Spaces deiined by said plates 2tprovide a plurality of alternate openings tl. The lower ends of sadplates 23 are adapted to receive and support by means of engaging screwsit a ring plate t, having a central opening 2l and a plurality orapertures it made in its body. vSaid opening 2l is ol a diameterconsiderably smaller than the diameter or cap it.

Adjacent the upper end of cylindrical casing l@ a plurality oi rows ofapertures 2t are made. Closure t@ having a central round opening tl, isset over the upper end of cylindrical casing it. Said closure t@ is ofgreater diameter than the diameterA oi cylindrical casina it and isprovided at a downwardly depending shirt horizontal path o saidapertures it.

Pipe tl connected. with the lower end o cylin1 drical casing it) formsmeans tor supplying fuel into said casing.

or said cylindrical casing lll which is below heme plate 2l defines thecorn,- hustion chamber. it liquid hiel, such as oil is used, the saulenowing from pipe 33 will spill upon bottom il where it will burn. Airpassing through opening it dened by said collar it will iirst enter capid and through apertures l@ into 'chamber il where it will becomepreheated. Thereupon air jtrom said preheating chamber il will passthrough apertures iQ into the combus= tion chamber within cylindricalcasing lli dis voccur so that the intended to be positioned within allyinto opening 21 and openings 24.

All gases eventually will pass into the supplementarycombustion chamberdisposed` above baille plate 2| and drical casing to flow of air throughsaid aper- 32 acts as a retarding means. gases will pass to the outsidetures 2.0 skirt Finally the resulting combustion through opening 3| inclosure 30 of the burner.

To prevent spilling of fuel beneath the burner particularly when anoverow of fuel should same would :how through the lowennost apertures I9and I8, pipe 34 may be provided to frictionally engage by its verticalend collar I3. The horizontal portion of said pipe 34 will carry theoverown fuel beyond the immediate connes oi' the burner.

Burner such as herein shown and described is a stove 35 shown by dottedlines, which has bottom 36 upon which the burner may be positioned. Thestove may be further provided with supporting legs 31, door 38, aplurality of baille plates 39 placed in a staggered relative position,and a flue I0.

While there is described herein a embodiment of the present invention,

therein without departing from the spirit and scope of the invention asclaimed.

What I claim as new is: i1'. A burner comprising a casing, said casingconstituting a combustion chamber, the bottom of said casing beingprovided with an opening,

I perforated shells within the upper end of cylin. l

genaues 2. A burner comprising a casing including a bottom tray adaptedto receive a liquid fuel, said tray being provided with. an opening. apair of overlying said opening, each o1' said shells including acylindrical upright portion `and a dome portion, said shells being in aconcentric spaced relative the two shells being on different horizontalplanes, the two shells constituting an air preheating perforations insaid outer shell, and means for admitting fuel to the combustion chamberexternally ofthe shells.
